Abstract

A magazinable strip of sealing clips (10) for bags and tubes, whose individual clips each consist of a clip bottom (14) and two legs (16, 18) and are connected with each other at the ends of the legs, is formed such that the sealing clips (10) are widest adjacent the clip bottom (14), and the width of the adjoining legs (16, 18) of two adjacent sealing clips (10) unilaterally decreases to less than half the maximum width alternatingly towards the one and the other longitudinal side. The longitudinal sides (32'', 34'') of the two legs (16, 18) resting against each other upon closure of the sealing clip can have locking teeth which restrict a springing back of the legs of the sealing clip when the same has been closed.

Description

But the clip bar of the automatic feeding that pocket and flexible pipe are sealed

But the present invention relates to the clip bar of automatic feeding that pocket and flexible pipe are sealed, the independent clip of wherein each by clip at the bottom of and two footing constitute, and interconnect in the footing end.

Usually by originally constituting for flat basic section, in order to process it with automatic closing appliance, it forms the rectangular of a single clip of U-shaped that links together to aforesaid sealing clip bar.Be sealing pocket or flexible pipe, pocket or flexible pipe draw in and form an end, and are inserted into the U-shaped sealing clip under the clip bar separates.Then, by sealing clip being sealed with two footing of U-shaped sealing clip are crooked relatively mutually.In this process, the free end of footing presses mutually and flattens.The closed process of this prior art and the explanation of sealing clip can be found in DE-PS3715626.

The disadvantage of these known sealing clips is, draws in the flexible pipe that forms an end or the cross-sectional plane of pocket to be positioned at narrow relatively scope, to guarantee that sealing not only reliably but also tight.When terminal cross-sectional plane was too big, the free end of footing can not press mutually, so pocket or flexible pipe can not seal reliably.On the other hand, when terminal bench section too hour, before being compressed fully endways, two footing of sealing clip have just at utmost been flattened, therefore, pocket or flexible pipe can not closely seal.In addition, the seal force during sealing is also relatively big.

For eliminating this shortcoming, the footing width of sealing clip is reduced inversely towards free end, and like this, after closing step, footing is placed adjacent partly.Know by US-PS2855647, on flexible conveyer belt, use the single clip of clamping such shaping from the adhesion mode one by one, but by this way they are made automatic feeding.Another solution is disclosed among the DE-GM1960244; In this document, single clip is connected to each other together at bottom section, must they could be separated from each other with the curved certain angle of rectangular longitudinal direction.In normally used automatic closing appliance, can not use this a kind of clip: can not use another kind of clip; In addition, their manufacturing cost is much more expensive than the described clip bar of beginning.

Therefore the objective of the invention is to propose a kind of sealing clip bar, its single clip interconnects in the end of footing, and is applicable to the big scope of different terminal cross-sectional planes.

This purpose is solved by the sealing clip bar that starts described type, these sealing clips are the wideest at the clip base place, and the width that adjoins footing of two adjacent sealing clips uniaxially between their clip base ends and their interconnective terminals is reduced to less than they maximum widths half, and wherein width is provided with towards another vertical side towards a vertical side alternately along the reduction of rectangular direction again.

With the footing width along rectangular unidirectional alternately reduction in addition, thereby this wonderful recipe that difformity or the different sealing clip of arranging always can be continuous mutually, but make and to use the sealing clip bar of producing the interconnective automatic feeding in footing end according to the described sealing clip of US-PS2855647.But when handling this sealing clip bar, its consequence is, same clip, and the seam when sealing between the adjacent footing is different alternately with follow-up clip with the leaning angle that the shell end longitudinal axis is become, and but, this can not constitute problem.

By sealing clip bar of the present invention, can satisfy the sealing that pocket or flexible pipe draw the different end diameters that form in; The diameter difference of sausage end can allow to reach 40%.In addition, sealing clip of the present invention required power only be of the prior art half.Another advantage is that the making of sealing clip bar is very easy; Compare material with traditional sealing clip bar and can save about 25%.

A variation scheme of sealing clip is a footing at contiguous their free end place, and its width is a unmodified.Adopt this method can increase the area that osed top sealing clip footing laterally overlaps mutually, like this, the variation range that terminal cross-sectional plane allows becomes bigger.

But, because the elasticity of sealing clip material and put on power on the sealing clip by sealing clip osed top terminal material, in case when automatically closing appliance the power on the sealing clip of acting on reduced, the footing of the sealing clip in the sealing clip bar of the present invention may rebound.This bounce-back may be directed at disadvantageous non-compactness.In sealing clip of the present invention, but in known sealing clip too, after the sealing clip sealing, article two, vertical side of footing leans on mutually, for reducing this disadvantageous non-compactness, all sealing clips are provided with the locking tooth in corresponding vertically side, with the bounce-back of restriction sealing clip sealing back sealing clip footing.At this moment, till the footing of sealing clip can only rebound and be meshing with each other to their locking tooth.

Embodiment to the sealing clip of the present invention's proposition describes referring now to accompanying drawing, wherein:

Fig. 1 is the local birds-eye view that launches of sealing clip bar;

Fig. 2 is the front elevation of clip bar section among Fig. 1;

Fig. 3 is the lateral plan of sealing clip in the clip bar;

Fig. 4 is the front elevation of sealing clip when centering on endcapped;

Fig. 5 is the birds-eye view of osed top sealing clip among Fig. 4;

Fig. 6 is the more new construction expansion drawing of sealing clip bar among Fig. 1;

Fig. 7 is the another more new construction expansion drawing with locking tooth that the sealing clip bar is arranged among Fig. 1; And

Fig. 8 is the birds-eye view of osed top sealing clip among Fig. 7.

The raw MAT'L of making the sealing clip that the present invention proposes is all bands of unmodified plastically deformable of width and thickness.V-arrangement zone 12 is gone in punching press alternately from this material, thereby has drawn the expansion of the sealing clip bar that is made of interconnective sealing clip 10, by shown in Figure 1.Zone 12 must be a V-arrangement not necessarily, sees Fig. 6.At expansion drawing (Fig. 1, can see Fig. 6) that each sealing clip 10 is substantially by 14 constituting at the bottom of the clip, two

footing

16 and 18 extend from its side, they 14 continue uniaxiallies to their

end

20 and 22 and phase down at the bottom of the clip, and reduce to below half of their maximum widths in the different vertically sides of sealing clip 10.Like this, each

footing

16 and 18 has the parallel vertical side 28 and 30 of banded relatively raw MAT'L line of centers separately, and the vertical side 32 of bevelled and 34.

End

20 and 22 in

footing

16 and 18 is provided with connecting

panel

24 and 26, and sealing clip 10 interconnects herein.

Behind stamping procedure, on automatic angle bender, band is curved the sealing clip 10 of U-shaped.In the embodiment shown in Figure 2,14 still is flat during bending at the bottom of the clip, and

footing

16 and 18 is then upright vertically.To horizontal extension, thereby the sealing clip 10 that all are connecting on the bar is all to same direction opening (in Fig. 2: towards upward to) from

footing

16 and 18 for connecting

panel

24 and 26.

Fig. 3 has clearly showed with the

opposed footing

16 and 18 of the corresponding U-shaped sealing clip of Fig. 2 and 14 has phased down to footing

end

20 and 22 at the bottom of the clip alternately.

When sealing sealing clip 10, its connecting

panel

24 and 26 is not directly to be superimposed with each other, but is drawn towards the both sides mutually, thereby makes profile shown in Figure 2 form profile shown in Figure 4.Sealing clip 10 is fully around terminal 36.Fig. 5 is the top view of osed top sealing clip among Fig. 4, it shows that footing 16 and 18 leans on mutually with the vertical side 32 of their inclination and 34, even when

footing

16 and 18 is promoted separately from osed top terminal 36, or since their elasticity after sealing, when slightly rebounding, also can reliably osed top end 36 be closed.

Sealing clip 10 depends on the diameter of closed end in the definite shape after the sealing: when diameter was very big,

footing

16 and 18 the vertical side 32 of inclination and 34 were not in contact with one another; However, they are laterally overlapping mutually, thereby end is closed reliably.On the other hand, when end diameter is very little, at closed period, footing 16 and 18 on their most length mutually along moving; Simultaneously, at the bottom of the whole sealing clip 10, particularly clip 14, become distortion.So after sealing, footing 16 and 18 vertical side 32 of inclination and 34 elastic forces that caused by the distortion of sealing clip 10 are pressed against together mutually.

As already described, when making the sealing clip bar, the section 12 under the staggered punching press not necessarily must be a V-arrangement.As shown in Figure 6, section 12 ' has other shape, and footing 16 ' and 18 ' has the width that is equal in their ends, and like this, the diameter of terminal section can change in a bigger scope.At extreme case, indentations section even can be rectangle.

Opposite with the sealing clip among Fig. 1, the sealing clip among Fig. 6 can not be distorted sealing when having especially little diameter terminal, because at closed period, the footing 16 ' and 18 ' the end sections that is parallel to each other can move through mutually.When their width of end sections just in time is a half of sealing clip maximum width, after sealing, footing 16 ' and 18 ' just laterally is in contact with one another.

Different with sealing clip shown in Figure 1, sealing clip shown in Figure 7 also has locking tooth 40 in addition, and they are pressing the opening of osed top sealing clip.Each locking tooth 40 be arranged on contiguous footing 16 " and 18 " end 20 " and 22 ", be positioned on those vertical sides, when the closure clamp period of the day from 11 p.m. to 1 a.m, as shown in Figure 8, they are leaning on mutually.Each locking tooth 40 comprises locking surface 42 and slip surface 44.Locking surface 42 roughly is vertically to makes sealing clip 10 " the band line of centers and extend.Relative this line of centers, slip surface 44 has than the comparatively smooth angle in locking plane 42, and and locking plane 42 be formed in sealing clip 10 together " clip at the bottom of 14 direction bevelleds locking tooth 40.

When sealing as sealing clip among Fig. 1 to 6, at closed period, sloping portion 32 shown in Figure 7 "/34 " move through mutually.This is directed at two footing 16 " and 18 " locking tooth 40 move mutually with their part slip surfaces 44 at least and pass through.In when sealing, so two footing 16 " and 18 " slip surface 44 parts lean on mutually.After the sealing, automatically closing appliance acts on sealing clip 10 " on power reduce sealing clip 10 immediately " footing 16 " and 18 " act on sealing clip 10 owing to their elasticity with by end 36 " on power be tending towards rebounding.During this rebounds, two footing 16 " and 18 " locking surface 42 have at least and severally move in opposite directions mutually, till they lean on mutually.As long as have at least several locking surfaces 42 to lean on footing 16 mutually " and 18 " just can not rebound sealing clip 10 again " can not continue again to open.State shown in Figure 8 just can reach.
